Oakland is 14-49 in their last 63 game one’s of a series and 1-5 in their last 6 Monday games. The over is 5-2 in Oakland’s last 7 Monday games. Seattle is 1-5 in their last 6 Monday games. The under is 4-0 in Seattle’s last 4 home games and the under is 4-0 in their last 4 games against the AL West. Oakland is 8-26 in these two teams last 34 head to head meetings.


Oakland comes into this game on a losing streak and still has the worst record in the MLB. Seattle is also below .500 on the year, but they have a pretty good pitching staff. Seattle is starting Luis Castillo, who has good numbers on the season, but he has struggled in his last few starts. Oakland is starting Kyle Muller, who has allowed 16 earned runs over his last 13.1 innings pitched. I like the over in this game.
